The AKM Currentier™ CQ / CZ Series Current Sensors are open-type current sensors using a Hall sensor, which outputs the analog voltage proportional to the AC/DC current. Very thin film is used as the Hall sensor, which enables the high-accuracy and high-speed current sensing. Coreless ultra-small surface mount package realizes the space-saving.
The CQ / CZ current sensors have linear sensing ranges from +/- 8.5A to +/- 129A (20A to 60A RMS), depending on the specific part. Response times as low as 0.5uS, and bandwidth up to dc to 1.5mHz. All the sensors are very low noise, <3mV.
